Lobularia plant named ‘Inlbumokni’

ABSTRACT

A new and distinct cultivar of  Lobularia  plant named ‘Inlbumokni’, characterized by its compact, outwardly spreading, mounding to trailing plant habit; freely branching habit; freely and continuous flowering habit; relatively long flowering period; light yellow-colored flowers; and good garden performance.

Botanical designation: Lobularia maritima.

Cultivar denomination: ‘INLBUMOKNI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lobularia plant, botanically known as Lobularia maritima and hereinafter referred to by the name ‘Inlbumokni’.

The new Lobularia plant is a product of a planned breeding program conducted by the Inventor in Heidesheim, Germany. The objective of the breeding program was to develop new compact and trailing Lobularia plants with numerous sterile flowers and long flowering period.

The new Lobularia plant originated from a cross-pollination conducted by the Inventor during the summer of 2014 in Heidesheim, Germany of a proprietary selection of Lobularia maritima identified as code number Lo13-4002-21, not patented, as the female, or seed, parent, with a proprietary selection of Lobularia maritima identified as code number Lo13-4000-2, not patented, as the male, or pollen, parent. The new Lobularia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heidesheim, Germany in May, 2015. Asexual reproduction of the new Lobularia plant by vegetative terminal cuttings in a controlled greenhouse environment in Heidesheim, Germany since June, 2015 has shown that the unique features of this new Lobularia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lobularia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Inlbumokni’. These characteristics in combination distinguish ‘Inlbumokni’ as a new and distinct Lobularia plant:

-   -   1. Compact, outwardly spreading, mounding to trailing plant         habit.     -   2. Freely branching habit.     -   3. Freely and continuous flowering habit.     -   4. Relatively long flowering period.     -   5. Light yellow-colored flowers.     -   6. Good garden performance.

Plants of the new Lobularia differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Lobularia are more freely branching and         denser than and not as open as plants of the female parent         selection.     -   2. Plants of the new Lobularia have larger flowers than plants         of the female parent selection.     -   3. Flowers of plants of the new Lobularia are more yellow in         color than flowers of plants of the female parent selection.

Plants of the new Lobularia differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Lobularia are denser and more uniform than         plants of the male parent selection.     -   2. Plants of the new Lobularia have slightly smaller flowers         than plants of the male parent selection.     -   3. Flowers of plants of the new Lobularia are light yellow in         color whereas flowers of plants of the male parent selection are         white in color.

Plants of the new Lobularia can be compared to Lobularia maritima ‘DLOBU20’, disclosed in U.S. Plant Pat. No. 25,142. In side-by-side comparisons, plants of the new Lobularia differ from plants of ‘DLOBU20’ in the following characteristics:

-   -   1. Plants of the new Lobularia are more vigorous than plants of         ‘DLOBU20’.     -   2. Plants of the new Lobularia are more trailing than plants of         ‘DLOBU20’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Lobularia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Lobularia plant.

The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘Inlbumokni’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of ‘Inlbumokni’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in 10.8-cm containers in a glass-covered greenhouse in Loudon, N.H. and under cultural practices typical of commercial Begonia production. During the production of the plants, average daily temperatures ranged from 19° C. to 21° C. Plants were grown under long day/short night conditions and were pinched three weeks after planting. Plants were 14 weeks from planting when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except were general terms of ordinary dictionary significance are used. Measurements were taken on individual plants.
